“The probability of global catastrophe is very high,” the Bulletin of the Atomic Scientists warned in setting the Doomsday Clock 2.5 minutes before midnight earlier this year. On nuclear weapons and climate change, “humanity’s most pressing existential threats,” the Bulletin’s scientists found that “inaction and brinkmanship have continued, endangering every person, everywhere on Earth.”
Every day, it seems, brings with it fresh new horrors. Mass murder. Catastrophic climate change. Nuclear annihilation.
It’s all enough to make a reasonable person ask: How much longer can things go on this way?

Nate, with lashing winds of 90 miles per hour, sprinted north Saturday morning across the Gulf of Mexico. The Category 1 storm, rumbling north-northwest at 26 mph, was 180 miles from the mouth of the Mississippi River and 265 miles from Biloxi, Mississippi, the hurricane center said in its latest advisory.
.
“A hurricane warning is in effect for portions of the northern Gulf Coast from Louisiana to Alabama, with the strongest winds expected to occur primarily to the east of the center,” said the hurricane center, which expanded its tropical storm warning east to Indian Pass, on the Florida Panhandle.

Archaeologists working at the Saqqara necropolis, a large burial ground south of the Great Pyramid of Giza in Egypt, have recovered the tip of an obelisk more than 4,300 years old; it’s one of the largest fragments from an ancient stone monument ever found.
The Swiss-French mission, headed by professor Phillippe Collombert, uncovered the upper part of the monument, built in 2,350 B.C. in the Old Kingdom era during the reign of Ankhnespepy II.

Even 34,000 years ago, our ancestors knew incest was a bad idea. Analysis of ancient human remains discovered in Russia has revealed that even among an extremely small society, inbreeding did not take place. This arrangement suggests these early humans mated outside their own clans, instead of risking the problems that arise from having sex with their relatives.
Researchers led by Martin Sikora, from the University of Copenhagen, Denmark, were looking at human remains found at the Sunghir burial site. This Upper Paleolithic archaeological site represents some of the earliest evidence of Homo sapiens in Europe. The four individual males found there lived between 34,600 and 33,600 years ago. Two of them were children and had been buried head to toe.
In their study, published in Science, the team analyzed the genomes of all four, looking at the genetic diversity between them. To the researchers surprise, they found they were unrelated to each other, despite being part of what would have been a very small group of maybe 25 people—humans had only just arrived in western Eurasia, so had not had long to build up a significant population.

‘Predictive policing’ is a powerful new tool for law enforcement, but critics see big ethical problems.
Editor’s note: NBC News MACH has partnered with the American Museum of Natural History to present three documentary films at the Margaret Mead Film Festival, which will be held in New York City from Oct. 19-22. In “Pre-Crime,” filmmakers Monika Hielscher and
Matthias Heeder examine the rise of predictive policing, which aims to stop crime before it occurs. The film led MACH to explore this new tool for law enforcement — its power and potential peril.
We all know police officers respond to crimes after the fact. But what if cops could learn about crimes before they occur — and take steps to prevent them? That’s the promise of predictive policing, a high-tech approach to public safety that uses data about previous crimes to forecast new criminal acts.
It’s a bit like weather forecasting, only for crime: At the beginning of their shifts, officers review a map showing areas where crimes are expected to occur, based on arrest records and the dates and locations of recent crimes. The cops review the information and then head out on their beats, armed with information of where they should go at which times — and even who the bad guys are likely to be.

After killing at least 22 people in Nicaragua and Costa Rica, Tropical Storm Nate is on a collision course with the northern U.S. Gulf Coast. Southeast Louisiana, including vulnerable New Orleans, lies in the path.
The storm, which is predicted to intensify into a hurricane, should make landfall between late Saturday night or early Sunday morning. Damaging winds and flooding threaten the region from roughly Morgan City, La., to Pensacola, Fla.

Rainer Weiss, a professor at the Massachusetts Institute of Technology, and Kip Thorne and Barry Barish, both of the California Institute of Technology, were awarded the Nobel Prize in Physics on Tuesday for the discovery of ripples in space-time known as gravitational waves, which were predicted by Albert Einstein a century ago but had never been directly seen.
In announcing the award, the Royal Swedish Academy called it “a discovery that shook the world.”
That shaking happened in February 2016, when an international collaboration of physicists and astronomers announced that they had recorded gravitational waves emanating from the collision of a pair of massive black holes a billion light years away, it mesmerized the world. The work validated Einstein’s longstanding prediction that space-time can shake like a bowlful of jelly when massive objects swing their weight around, and it has put astronomers on intimate terms with the deepest levels of physical reality, of a void booming and rocking with invisible cataclysms.

Three European-born scientists were awarded the Nobel Prize in Chemistry on Wednesday for developing a new way to assemble precise three-dimensional images of biological molecules like proteins, DNA and RNA.
Their work has helped scientists decipher processes within cells that were previously invisible, and has led to better understanding of viruses like Zika. In the future, their techniques could offer road maps in the development of drugs to treat diseases.
The winners are Jacques Dubochet, a retired biophysicist at the University of Lausanne in Switzerland; Joachim Frank, a professor at Columbia University in New York; and Richard Henderson, a scientist at the British Medical Research Council’s Laboratory of Molecular Biology in Cambridge, England.
The Nobel committee said the technique, cryo-electron microscopy, produces “detailed images of life’s complex machineries in atomic resolution.”

Jeffrey C. Hall, Michael Rosbash and Michael W. Young were awarded the Nobel Prize in Physiology or Medicine on Monday for discoveries about the molecular mechanisms controlling the body’s circadian rhythm.
The three scientists used fruit flies to isolate a gene that controls the rhythm of a living organism’s daily life. Dr. Hall, Dr. Rosbash and Dr. Young were “able to peek inside our biological clock,” helping “explain how plants, animals and humans adapt their biological rhythm so that it is synchronized with the Earth’s revolutions,” the Nobel Prize committee said.
By examining the internal workings of fruit flies, the investigators helped determine that the gene they were analyzing encoded a protein that accumulated in cells at night, and then degraded during the day.

It was well past midnight when Michael Abrams, Claire Bedbrook and Ravi Nath crept into the Caltech lab where they were keeping their jellyfish. They didn’t bother switching on the lights, opting instead to navigate the maze of desks and equipment by the pale blue glow of their cellphones. The students hadn’t told anyone that they were doing this. It wasn’t forbidden, exactly, but they wanted a chance to conduct their research without their PhD advisers breathing down their necks.
“When you start working on something totally crazy, it’s good to get data before you tell anybody,” Abrams said.
The “totally crazy” undertaking in question: an experiment to determine whether jellyfish sleep.
It had all started when Bedbrook, a graduate student in neurobiology, overheard Nath and Abrams mulling the question over coffee. The topic was weird enough to make her stop at their table and argue.
